Fluorexon Usage And Synthesis

Chemical Properties	orange crystals
Uses	Calcein is used for determination of Ca in biological systems. Indicator for the fluorimetric determination of calcium in presence of Mg by complexometric titration.
Uses	Calcein is a anthene that is commonly used for the fluorometric determination of calcium in solution. As this form of calcein is not membrane permeable, it can be used in assays that evaluate membrane integrity. Calcein can also be used as a fluorescent indicator for fluoride, iron, and mer-cury. [Cayman Chemical]
Uses	Calcein could be useful for magnetic resonance imaging-guided sonodynamic combination therapy.
Definition	ChEBI: Calcein is a xanthene dye. It has a role as a fluorochrome. It is functionally related to a fluoran.
Biological Activity	Calcein is a fluorescent dye and self-extinguishing probe that can be used as an indicator of lipid vesicle leakage, as well as a complex indicator for EDTA calcium titration and fluorescence determination of calcium.
